Debunking 6 Myths About Geothermal HVAC Systems in Charleston, SC

Geothermal HVAC systems are an environmentally-friendly way to heat or cool your home in Charleston, SC. They take advantage of the earth’s natural and even temperature to provide heating in the winter. And while geothermal HVAC systems offer countless benefits, here are a few common misconceptions about them that we want to set straight.

1. Geothermal HVAC Systems Are Expensive

Although geothermal HVAC systems are more expensive up front, they can help you save a considerable amount of money over their lifespan. The additional cost is usually recouped during your savings with energy rebates from your utility company and tax credits from the government.

As a renewable energy resource, ground source heat pumps can be green and cost-efficient. Installing a geothermal HVAC system in your Charleston, SC, home also allows you to take advantage of up to 30% federal tax credit.

2. Geothermal HVAC Installation Requires a Large Yard

Based on the characteristics of the site selected for geothermal HVAC installation, the earth loops can get buried vertically or horizontally. Horizontal loop systems require a lot of space. This is because several trenches, with a depth of 6 to 10 feet each, need to get dug up to provide enough space to install the loops.

The installment of a vertical system requires less space, as it can fit in one hole with a depth of about 200 to 600 feet. The hole should be 6 inches in diameter to allow the drilling equipment to fit into the hole. In cases where an aquifer is available nearby, the vertical system is ideal and only requires a few feet of the land surface.

3. Geothermal HVAC Systems Only Work in Heating Mode

Properly installed and sized geothermal ground source heat pumps are capable of providing adequate heating in the winter and cool air in the summer. These systems combine the natural temperature of the earth with a heat exchanger to distribute heat into your home.

At 15 feet below the surface, the ground maintains a temperature of 55 degrees Fahrenheit all year round. This constant temperature provides a continuous source of energy to heat or cool your home.

4. My Home Is Too Old for a Geothermal System

Like any HVAC system, geothermal systems can also get retrofitted in older homes. Most geothermal systems are easy to install. They are compatible with a variety of home systems that use ductwork to deliver heated or cooled air.

In addition, installing a geothermal HVAC system ultimately increases the value of your home with its energy-efficient air conditioning and heating capabilities. Geothermal systems also help to reduce your carbon footprint, freeing you from the guilt of contributing to greenhouse gas emissions.

5. Geothermal Systems Require a Lot of Maintenance

Since geothermal HVAC systems are all-in-one, they require much less maintenance than conventional air conditioning and heating systems. Geothermal HVAC components get buried several feet below the earth and never come into contact with the surface. This ensures the system is well protected from the elements and does not attract pests.

In addition, there is little chance of damage from vandalism since there are no exposed parts. Conventional HVAC systems, on the other hand, are usually exposed to the elements, making them vulnerable to damage. As a result, a lot of hard work and extra expenses go into maintaining them.

6. Geothermal Systems Are Noisy

Since geothermal HVAC systems are loop-closed, they are quieter than conventional HVAC systems. Because these systems do not use exterior ductwork to regulate heating or cooling, there are no noisy fans or compressors outside your home.

Most of the geothermal HVAC system is installed several feet below the surface of your property to ensure they do not disturb your neighbors. This makes them extremely quiet during their operations in comparison with conventional HVAC systems.
